Right now my friend calls me and he asked me to go on H-T and find out what his compression should be. How much psi should it be at on a D16Y8 motor.

TIA.

 

u have been here for a while. do you ever search for your answer's?

Yup but I need to know ASAP and I did searched but didn't find the answer im looking for and im searching as we speak. Thanks for nothing.

 

He says he got 150 on all four pistons and the mechanic is telling him its normal and that's what it should be but my friend thinks otherwise and right now hes still over there and on the phone with me.

Sounds like he may have done the test wrong. I did as well. Hold it WOT with all plugs removed. My comp numbers went from 150 to 210.

 

no its not that im asking if those numbers are right its just my car feels like the compression is low and he says 150 is normal and i dont think it is the motor i had befor wich was the same felt way faster and responded better too

 

I heard the compression ratio on a d16y8 was 11:1 but i dont totally know i personally thought it was lower

No way not 11:1. More like 9:6:1 or something of the like.

 

Compression should be around 180 to 190 on all four cylinders.

 

what do i do to fix my compression

Did you read the link that I posted? I got the same numbers (150) with my test, but I didn't do it at WOT. When I re-did the test, it came out to 210. 150 is an okay number for alot of motors, but Honda motors are pretty high compression, and 180 is a good number.

Is there something specifically wrong with your car that you had this test done in the first place, besides feeling sluggish?

The only way to 'fix' compression would be internal servicing, most likely rings. Read my liink to see if the mechnic did the test properly, because you may not have a compression problem at all.

 

i blew my motor so compared to the one i had befor my new one feels more sluggish. now whether he did it right or wrong somthin is still wrong with my car so i dont care if he did it at wot
